Definitions
- the invention relates to an automatic control unit for controlling the gearbox of a vehicle.
- the invention relates to an automatic control unit for controlling the gearbox of a vehicle, of the type in which, while respecting the sequences of a normal gear shifting, these latter are actuated by electronic means connected to a microprocessor.
- the known devices for the automatic control of the gearbox require to provide, downstream of the engine, an hydraulic torque converter and an epicyclical unit with three or four forward gears, with oil bath clutch for locking the gear.
- An object of the invention is to provide an automatic control unit for controlling a mechanical gearbox, which will reduce the controls in driving the vehicle, thus reducing the consumption of fuel.
- Another object of the invention is to provide an automatic gearbox which will attain the same high efficiency of a manual type gearbox, thus avoiding the use of low efficiency means, such as the hydraulic torque converter peculiar to the known automatic gearboxes,whichwillenable also to program various driving manners, including the drive with low consumptions which result in being lower even than those obtainable with a manual control.
- a further object of the invention is to propose an automatic control unit adapted to be applied on a conventional manual gearbox without having to make considerable structural modifications to it, so as to obtain low manufacturing costs.
- the proposed automatic gearbox unit utilizes electric controls which require additional power sources, inasmuch as said controls exploit the feeding means existing on the vehicle.
- the invention proposes to provide an automatic control unit for controlling the gearbox of a vehicle applied to a clash gear or constant mesh gearbox of conventional type and in which the selection of the neutral position, the reverse movement position and the first speed position is controlled manually, characterized in that the rods of the forks which carry out the throw in and the throw out of the speeds higher than the first speed are operated by motor means which actuate suitably shaped guides along which the said rods slide following combined ways to sequentially actuate the said forks; said motor means, in their turn, being actuated by electronic processor means, to which there are further connected: sensor means sensing the position of the gear lever, the speeds higher than the first speed which are thrown in by said motor, the speeds in output from the engine and on the driving wheels, the clutch opening and closure position, respectively, the position of the foot brake and accelerator pedals, as well as means actuating the opening and the closure of the clutch and the feeding member which feeds the fuel to the engine; said processor means being
- Fig. 2 Visible in Fig. 2 is an arm 23 connected to the gearbox lever 10 by means of linkages (not shown), and to a fork 22 having prongs 24 supported thereon which operate a sleeve 24a provided with an external toothing and an inner groove and slidable on the hub 26; all this is shown in Fig. 3 in which the gearbox of the vehicle is represented.
- the wheel 25 receives the motion from the lever 79 through the free wheel 80 indispensable for allowing the relative motion between the wheel 79 and the wheel 25 at the speeds higher than the first speed, the wheel 25 and the sleeve 24a being always in mesh for said speeds.
- sleeve 24a represented with full lines is in the neutral position; by manually acting on the lever 10 the fork 22 is traversed in the direction of the arrow I and makes mesh the inner groove of the sleeve 24 a with the wheel 25, thereby rigidly connecting this latter to the wheel 26 and engaging the first speed.
- each rod which are opposite to those provided with the respective forks are slidably guided in respective circumferential grooves 35,36 and 37 of a drum 38 shown in axial cross-section in Fig.4 and in development in Fig. 5.
- the parts 72, 73 and 74 of the rods 28, 29 and 30 slide within slots 75, 76 and 77 visible in Fig. 5 and formed on a reaction plate 71, fixed on the gear case 81.
- the drum 38 mounted on bearings 39, is rotated by the motor M c (Fig. 1) whose shaft 40 supports a gear 78 on which the gears 41 are engaged which, in their turn, mesh with toothed portions 42 of the inner surface of the drum 38.
- Shown in Fig. 3 are the sleeves 31, 43 and 44 in which the forks supported by the rods 28, 29 and 30, respectively, are engaged in a known manner.
- FIGs 6 and 7 show the clutch operating unit which, as shown in Fig. 1, is controlled by the motor M whose shaft 45 supports a gear 46 which meshes with a denction gear 46 keyed on an axle 48 toothed at 49, with which the rack portion 50 of a rod 51 pivoted to the linkage 52 (Fig.1) controlling the clutch 14 engages.
- a freewheel 53 Also mounted on the driving shaft 45 is a freewheel 53 whose construction will be described later.
- Fig. 7 Diagrammatically shown in Fig. 7 is also the support 82 connecting the gear case and the engine.
- Fig. 8 shows the accelerator control unit formed by a lever 54 pivoted at 55 and controlled by the electromagnet 16 (Fig. 1) through the rod 56.
- the lever 54 rotating, acts on a pivot 57 of the lever 58 which is also pivoted at 55 and one end of which is connected to the throttle 13 through a transmission member 59, while the other end is pivotally connected at 60 to a jacket 61 slidable outside a tube 65; interposed between the two elements is a preloaded spring 67 which renders resilient the gearbox control.
- the guide bushing 6 operated by the cable 64 of the accelerator; in addition, disposed between the tube 65 and a guide stem 63 guiding the cable 64 is a return spring 66 for the accelerator 12.
- the starting of the engine can be carried out only when the gearbox lever is in the neutral position, and the sensor S a allows starting the engine when the clutch is closed, this condition being obtained by means of the processor 21 which actuates the motor M f which, through the kinematic mechanism 45 + 50, traverses the rod 51 in the direction of the arrow B, and accordingly lever 52 closes the clutch 14.
- one of the sensord Sma (forward movement)or S rm (reverse movement) will close and will send current pulses to the motor M f to close the clutch 14, i.e. to traverse the rod 51 in the direction of the arrow B.
- the unit In passing from the speed I controlled in an entirely manual manner, as described above, to the higher speeds (II, III, IV and V sequentially) the unit acts automatically without requiring any further manual intervention.
- the processor 21 carries out the follwing passages sequentially:
- the rod 56 of the electromagnet E am is traversed in the direction of the arrow C in Fig.8, thus allowing the rod 59 to reach the position shown in this Figure, which corresponds to the maximum closure of the throttle 13, i.e. to the slow speed of the engine.
- This slow speed shifting condition determined by the electromagnet occurs also when the accelerator pedal is pressed thanks to the action of the preloaded spring 67 which opposes the pull of the accelerator cable 64.
